Let's start by a small set of tests, to eventually consider running more. The current list should then be: gem_mmap gem_pread_after_blit gem_ring_sync_loop gem_ctx_basic gem_pipe_control_store_loop gem_storedw_loop_render gem_storedw_loop_blt gem_storedw_loop_bsd gem_render_linear_blits gem_tiled_blits gem_cpu_reloc gem_exec_nop gem_mmap_gtt v2 add (Daniel Vetter) gem_exec_bad_domains gem_exec_faulting_reloc gem_flink gem_reg_read gem_reloc_overflow gem_tiling_max_stride prime_* Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
